Summary

Description
Русский: Экспериментальный аппарат Герца 1887 года.
English: Experimental circuit used by Heinrich Hertz in 1887 to discover the existence of radio waves. It is a spark gap radio transmitter (left) consisting of a dipole antenna made of two horizontal wires with metal plates on the ends to add capacitance, with a spark gap between them, attached to an induction coil powered by a battery. Pulses of high voltage applied to the antenna by the induction coil cause sparks across the spark gap, which excite standing waves of current in the antenna, causing it to radiate electromagnetic waves (radio waves). The waves were detected by a crude receiver consisting of a resonant loop antenna (right) made of a circle of wire, with a micrometer spark gap between its ends.
